Document Type and Number:

WIPO Patent Application WO/2019/062988

Kind Code:

A1

Abstract:

Disclosed are a temperature regulation method and temperature regulation system for a vehicle-mounted battery, the vehicle-mounted battery comprising a plurality of batteries connected in parallel. The method comprises the following steps: respectively acquiring a required power of a plurality of batteries connected in parallel; respectively acquiring an actual power of the plurality of batteries connected in parallel; and respectively regulating, according to the required power and the actual power of the plurality of batteries connected in parallel, the temperatures of the plurality of batteries connected in parallel. By means of the present disclosure, a heating power and a cooling power of each battery can be precisely controlled according to an actual state of each battery, and the temperature is regulated when the temperature of the battery is excessively high or excessively low, so that the temperature of the battery is kept within a pre-set range, thus preventing the performance of a vehicle-mounted battery from being affected by the temperature.
